2016 Earth Expeditions: ORACLES

Southern Africa produces almost a third of the world’s vegetative burning, which sends smoke particles up into the atmosphere, where they eventually mix with stratocumulus clouds over the southeastern Atlantic Ocean. The Observations of Clouds above Aerosols and their Interactions (ORACLES) study is investigating how these particles impact the stratocumulus clouds, which play a key role in both regional and global surface temperatures and precipitation, in order to help improve current climate models.

The Global Modeling and Assimilation Office (GMAO) works to maximize the impact of satellite observations in climate, weather and atmospheric composition prediction using comprehensive global models and data assimilation. To achieve this goal, the GMAO develops models and assimilation systems, generates products to support NASA instrument teams and the NASA Earth science program, and undertakes scientific research to inform system development pathways.

Assimilation systems have been developed for the atmosphere, ocean, and land surface. GMAO's long-term goal is an integrated Earth system model and assimilation system that treats the individual components in a more coupled and interactive manner. GMAO works within numerous national and international collaborations to support its mission.
